Has anyone had rotator cuff surgery with a dermal cadaver skin/tissue graft? I have a 4cm. and 5 cm. tear in my supraspinatus and infraspinatus tendons resulting from a fall. The tears are retracted to the point that they can't be repaired without a graft. Scheduled for surgery Wednesday. Unable to find a lot of info on this type of surgery. Any advice is appreciated! Thanks....Gayle
